Please give me an example of an an unnecessarily confusing excel formula.
Here is an example of an unnecessarily confusing Excel formula:
Copy code
=IF(NOT(ISERROR(VLOOKUP(A1,Sheet2!A:B,2,FALSE))),VLOOKUP(A1,Sheet2!A:B,2,FALSE),IF(NOT(ISERROR(VLOOKUP(A1,Sheet3!A:B,2,FALSE))),VLOOKUP(A1,Sheet3!A:B,2,FALSE),IF(NOT(ISERROR(VLOOKUP(A1,Sheet4!A:B,2,FALSE))),VLOOKUP(A1,Sheet4!A:B,2,FALSE),IF(NOT(ISERROR(VLOOKUP(A1,Sheet5!A:B,2,FALSE))),VLOOKUP(A1,Sheet5!A:B,2,FALSE),0))))
This formula uses a series of nested IF
and VLOOKUP
functions to search for a value in cells A1 of sheets 2 through 5 in a workbook. If the value is found, it returns the corresponding value from column B of the matching row. If the value is not found, it returns 0.
This formula is unnecessarily confusing because it uses multiple nested IF
and VLOOKUP
functions, which makes it difficult to understand what the formula is doing. A simpler and more readable way to write this formula would be to use a single VLOOKUP
function with an array of sheets as the lookup range, like this:
Copy code
=VLOOKUP(A1, {Sheet2!A:B, Sheet3!A:B, Sheet4!A:B, Sheet5!A:B}, 2, FALSE)
This formula uses a single VLOOKUP
function with an array of sheets as the lookup range, which makes it much easier to read and understand. It has the same behavior as the original formula, but it is much simpler and more concise.
